properties“CANDLE Properties”
A. Physical Properties:
• Solid
• Opaque partly transparent partly
• Waxy
• Melting
B. Chemical properties:
• Flammable
All things are made up of atoms. There are 92
different types of atoms, called elements.
Each element has different
properties.
The properties of matter can be grouped
into two categories: physical and
chemical properties.
Physical and
Chemical Properties
Look in book pg. 80 and pg. 96 to
find the definitions.
C. Physical Properties• 8 The Physical Properties to memorize:
Mass
Volume
Density
Conductivity (of heat or electricity)
Boiling point/melting point
State of matter
Solubility
Magnetism
(Which of these seems least like a physical property to you?)
Part A and B
Go to pg. 84 and 85
A. Chart: Fill out the chart.
B. Analysis: Choose one that is least
familiar to you, read about it, then
summarize what you read.

Boiling Pt/Melting Pt
• This is NOT burning!
• Not all things melt or boil!!
• Does wood melt?
• Most biotic (living or once-
living) things DO NOT melt!

• Similar to gas
• Electrically conductive
• Magnetic.
• “A sea of charged
particles”
Solubility… “Dissolvability”
The ability of a
substance to
dissolve in a
liquid
Why is this a
physical
property?
H. Crime Scene…
• List the physical and chemical
properties of object.
• Class will need to guess your
object.
Objects for the
tables…
Paper
Candle
Crayon
Christmas lights
Flash Light
Alka-selzer packet
Toy Car
• What are some physical
properties of salt?
Starter– Comp. notebook
Write the objective in your notebook:
Objective: To learn the chemical and physical
properties of elements on the periodic table.
Today: Quiz on properties. Bring colored
pencils, if you have any.
Intern: Please pass back papers today.
Chemical properties...1. Definition– Can only be observed as it
changes to a different type of matter.
(Changes to a new molecule.)
The ability to change into something new.
How it reacts with others.
2. Chemical Properties to memorize:
1. Flammability
2. Rustability
3. Reacts with water
4. Reacts with acid
3. Examples of chemical properties are...
Paper burns
Iron (Fe) rusts
CO2 doesn’t burn
Silver (Ag) doesn’t react w/water
Copper (Cu) reacts with Oxygen (tarnishes)
•During a chemical change, the substance may…
React
Rust
Tarnish
Corrode
Explode
Lets Review…Physical Properties: properties we can
measure without changing the identity of
the matter.
Chemical Properties: a substance’s ability
to change into something new. It can only
be observed while the change is taking
place.
(We use these properties to distinguish
chemicals from one another)
